A long bone is one that is cylindrical in shape, being longer than it is wide. ... Long bones are found in the arms (humerus, ulna, radius) and legs (femur, tibia, fibula), as well as in the fingers (metacarpals, phalanges) and toes (metatarsals, phalanges). Long bones function as levers; they move when muscles contract.

Are metacarpals short or long bones?

Medical Definition of Bone type

Short bones: Short bones also have a tubular shaft and articular surfaces at each end but are much smaller. The short bones include all of the metacarpals and phalanges in the hands, and the metatarsals and phalanges in the feet.

Why are phalanges considered long bones?

Answer and Explanation: Phalanges are classified as long bones, which may seem confusing as they aren?t actually very long in length. In order to be classified as a long bone, a body of the bone must be longer than it is wide. Long bones also have epiphysis, or growth plates, at the ends.
